Connect CF Card to PC
General
Preparation
Prior to removing the CF card in DN-60 and seeing your video as files
instead of clips, the MAKING MEDIA FILES process must be undertaken.
MAKE MEDIA FILES
This operation prepares the recorded content to be seen by a computer
by building the file wrappers around the recorded content and emulating
the computer’s operating file system. Two choices are available, FAT32
and NTFS and they are chosen by the SETUP FAT32/NTFS option.
Operating File System limitations
The FAT32 format is compatible with both Macs and PCs. This format
limits the size of a file to a maximum of 2GB, in DV that translates to
approximately 9+ minutes of video. A clip that lasts longer than 9min is
broken into multiple files each 2GB long with the last one making up the
remaining time. If the split files are strung on the time line of an NLE, no
frame is lost over the transition. In addition, FAT32 has a clip boundary
has a resolution of 2 seconds so the beginning of a clip other than the
first in a bin is most likely to contain the end of the previous clip, up to 2
seconds' worth. Conversely the end of a clip is most likely to be found in
the first file of the next clip. For an accurate correlation of clip numbers
between the VTR and the HDD mode, it is best to keep each clip longer
than 2 seconds and to have fewer than 97 per bin.
The NTFS format is fully compatible with PCs and is read compatible with
Macs. Its main advantage is that it does not impose a file size limitation to
the DN-60 resulting in one file per clip. NTFS’ clip boundary is frame
accurate and therefore has perfect correlation with clip numbers in the
VTR mode.
Note:
Some NLEs cannot accept file sizes greater than 40GB, make sure
your NLE is not one of them if you plan on shooting one continuous take
greater then 3 hours and using NTFS.
